The ROBOTC development team is happy to finally have a first BETA version of ROBOTC for LEGO Mindstorms with support for the EV3 available. This version is what we would call a “rough beta” version, but we’re happy enough with the progress made to make a version available for everyone to use. You will be able to install the 4.X Beta version alongside your ROBOTC 3.x installation, but keep in mind that this 4.X version will overwrite any other existing ROBOTC 4.X installation.

I am using a NXT motor on ev3. I setup the motors and sensor accordingly but when thew programs starts the motor will initialise itself to a fix position.

this only happen when i am trying to use step into

Yup, I'm definitely using wait1Msec. And sleep(1000) goes on for 10 seconds too. I tried sleep(100) and it lasts one second.

Re: ROBOTC 4.09 Beta 1 (EV3 Support) Available Now!

A question: I really want to try the new RobotC for EV3 but my team has scheduled a demo event that involves demoing the EV3 GyroBoy. Since I am not sure my GyroBoy RobotC port will work, I am hesitant to flash the firmware to RobotC 4.x. Is there a way to go back to LabView firmware if I need to?

Hello,

Great, it works !

MHTS:Yes, you can reflash your brick with the original firmware, with the Lego software.Alternatively, you can use a micro SD card with the RobotC firmware to boot on. Look for EV3LinuxImage_105X.raw.bz2 in the Firmware subdirectory, expand it and copy it on a 4GB (or more) micro SD with Win32diskimager (Windows) or dd if=EV3LinuxImage_105X.raw of=/dev/XXX (Mac OS X / Linux, XXX depends on your system).

i got the same problem too

tim what's this about? i get it when my robot is trying to compute equations

this is just the part where step into says the error started. when it computes moveValueB=, it 'crash' and gave that error

another critical bug found. EV3 Color Sensor mode can't be change. At Motor and Sensor page, i change Color(EV3) to Color detection mode, when i click apply, the pragma is still the same and when i go back into the setup page again, it changed back to reflected. Is there anyway I can manually type the code for Color mode?

If you want to configure a colour sensor as an actual sensor for colour, take a look at the samples in the sample folder. Go to File->Open Sample Program

EDIT: nthing

RobotC immediately crashes any time it tries to access the EV3 (flashing the firmware, pinging, downloading code, ...) brick in a vmware virtual machine. I tried this on vmware workstation 10.02 and (more importantly) on vmware fusion 6.03. Both times I used Windows 8.1 32 bit as guest OS. I would really appreciate if I could use RobotC for EV3 on my Mac using a VM.

Hello, I have successfully used RobotC 4.09 on my Macbook with Windows XP running into a VirtualBox VM. I just have added the "LEGO Group EV3 [0216]" device in the USB filter list.
